	~~==Etymology==~~		The '''infraorbital plexus''' is a network of nerves located in the [[face]], specifically beneath the [[orbit (anatomy)\|orbit]] of the [[eye]]. This plexus is primarily involved in the sensory innervation of the midfacial region, including the lower eyelid, side of the nose, upper lip, and cheek.
	The ~~term "Infraorbital Plexus"~~ is ~~derived from Latin. "Infra" means below~~, ~~"orbital" refers to~~ the eye ~~socket, and "~~plexus" is ~~used to describe a network~~ of ~~nerves or vessels in~~ the ~~body~~.

	==Anatomy==		== Anatomy ==
	The Infraorbital Plexus is formed by the infraorbital nerve, a branch of the maxillary nerve, which is the second branch of the trigeminal nerve. The infraorbital nerve exits the infraorbital foramen, a small hole in the maxilla (upper jaw bone), to form the infraorbital plexus. This plexus innervates the lower eyelid, the side of the nose, and the upper lip.

	~~==Clinical Significance==~~		The infraorbital plexus is formed by the branches of the [[infraorbital nerve]], which is a continuation of the [[maxillary nerve]] (V2), the second division of the [[trigeminal nerve]] (cranial nerve V). The infraorbital nerve exits the skull through the [[infraorbital foramen]], located just below the orbit.
	~~Due to its location and~~ the ~~areas it innervates~~, the ~~Infraorbital Plexus can be affected by various medical conditions and procedures. For instance~~, ~~trauma to~~ the ~~midface can potentially damage~~ the ~~plexus, leading to sensory loss in~~ the ~~areas it supplies. Additionally, in certain surgical procedures of~~ the ~~midface~~, the ~~Infraorbital Plexus may need to be anesthetized to ensure patient comfort~~.

	==~~Related Terms~~==		=== Branches ===
	* [[Infraorbital nerve]]
	* ~~[[Maxillary nerve]]~~		The infraorbital nerve gives rise to several branches as it forms the infraorbital plexus:
	* ~~[[Trigeminal nerve]]~~
	* [[~~Infraorbital foramen~~]]		* '''Palpebral branches''': These supply the skin and conjunctiva of the lower eyelid.
			* '''Nasal branches''': These innervate the side of the nose.
			* '''Superior labial branches''': These provide sensation to the upper lip.

			== Function ==

			The primary function of the infraorbital plexus is to provide sensory innervation to the midfacial region. It is responsible for transmitting sensory information such as touch, pain, and temperature from the skin and mucous membranes of the face to the brain.

			== Clinical Significance ==

			Damage or compression of the infraorbital plexus can lead to sensory disturbances in its area of distribution. This can occur due to facial trauma, surgical procedures, or conditions such as [[trigeminal neuralgia]]. Symptoms may include numbness, tingling, or pain in the affected areas.

'''Infraorbital Plexus'''

The '''Infraorbital Plexus''' is a network of nerves found in the face, specifically in the infraorbital region. It is a part of the [[Maxillary nerve]], which is itself a branch of the [[Trigeminal nerve]]. The Infraorbital Plexus provides sensory innervation to the midface, including the lower eyelid, upper lip, and the cheek.

==Etymology==
The term "Infraorbital Plexus" is derived from Latin. "Infra" means below, "orbital" refers to the eye socket, and "plexus" is used to describe a network of nerves or vessels in the body.

==Anatomy==
The Infraorbital Plexus is formed by the infraorbital nerve, a branch of the maxillary nerve, which is the second branch of the trigeminal nerve. The infraorbital nerve exits the infraorbital foramen, a small hole in the maxilla (upper jaw bone), to form the infraorbital plexus. This plexus innervates the lower eyelid, the side of the nose, and the upper lip.

==Clinical Significance==
Due to its location and the areas it innervates, the Infraorbital Plexus can be affected by various medical conditions and procedures. For instance, trauma to the midface can potentially damage the plexus, leading to sensory loss in the areas it supplies. Additionally, in certain surgical procedures of the midface, the Infraorbital Plexus may need to be anesthetized to ensure patient comfort.
